Carbon Filter Control Valve Features and Programming
Control Operation During A Power Failure
The SXT includes integral power backup. In the event of power failure, the control shifts into a
power-saving mode. The control stops monitoring water usage, and the display and motor shut
down, but it continues to keep track of the time and day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile memory and are stored indefinitely
with or without line power. The Time of Day flashes when there has been a power failure. Press
any button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will save the current valve position be-
fore it shuts down. When power is restored, the control will resume the regeneration cycle from
the point where power failed. Note that if power fails during a regeneration cycle, the valve will
remain in it's current position until power is restored. The valve system should include all re-
quired safety components to prevent overflows resulting from a power failure during regenera-
tion. The control will not start a new backwash cycle without line power.
Master Programming Mode
When the Master Programming Mode is entered, all available option setting displays may be
viewed and set as needed. Depending on current option settings, some parameters cannot be
viewed or set. Use the following chart to program your filter. You will use the highlighted val-
ues. Items not highlighted either do not require a change or do not appear in filter mode.
Entering Master Programming Mode
Set the Time Of Day display to 12:01 P.M. Press the “extra cycle”. Then press and hold the Up
and Down buttons together until the programming icon replaces the service icon and the Display
Format screen appears. The extra cycle button will serve as an “enter/save” button. The up
and down arrows are used to change the value of each parameter and the extra cycle button
saves the parameter changes and will move the control to the next programming parameter.
Exiting Master Programming Mode
Press the Extra Cycle button to accept the displayed settings and cycle to the next parameter.
Press the Extra Cycle button at the last parameter to save all settings and return to normal oper-
ation. The control will automatically disregard any programming changes and return to normal
operation if it is left in Master Programming mode for 5 minutes without any keypad input.
Soft Reset:
Press and hold the Extra Cycle and Down buttons for 25 seconds while in normal Service mode.
This resets all parameters to the system default values, except the volume remaining in meter immediate or meter de-
layed systems and days since regeneration in the time clock system.
Master Reset:
Hold the Extra Cycle button while powering up the unit. This resets all of the parameters in the unit.
Check and verify the choices selected in Master Programming Mode.
Please use the following chart to program the carbon filter control valve. Use the high-
lighted settings. Days between backwashes will be determined using the chart on page
#4. Some parameters will not be shown depending on the valve configuration.
